An identical skill list on 5 listings
These 5 listings' agent cards declare exactly the same skills — compared by each skill's id, name and description, ignoring case, spacing and each card's own hostname; for an MCP server that declares no skills, the tools it listed. That is a fact about the cards' text. It often means shared software or a shared template, but it does not tell us whether one operator runs them all or each is run separately. They are on 1 registrable domain, in 1 country.
